Anti-slosh liquid propellant tank for launch vehicles

摘要

A low profile slosh attenuation system is disclosed for liquid propellant tanks of a launch vehicle (100). The slosh attenuation system provides a desired level of slosh damping while reducing or eliminating the need for conventional high profile slosh barrier rings. In one embodiment, the slosh attenuation system is integrated into structural grids (300) used to construct a propellant tank. The invention results in substantial reduction in tank mass, construction complexity and cost.
